Seths - so glad that you now have the correct diagnosis for Seth, but I would be so angry like you are because of the time it's taken given you've been trying to get him diagnosed for 3 years with obvious signs
With regards to the food I'm not a lot of help as Ruben eats pretty much anything I give him, puréed or finger foods. The hv once told me that you have to offer a food between 15-20 times before you definitely put it on the 'not liked' list, so perseverance is key I think. Like skeet though when Ruben eats he can either be really easy to feed or not depending on his mood. If he's overtired I pretty much have to sing through the whole meal or he is grouchy as anything and try's to knock the bowl out of my hands and rubs the food all over his face!
Heaven - I'm probably not the best to answer since Ruben was my 5th baby and I definitely can't see DH agreeing to any more
Me and my sister are only 19 months apart and we hated each other growing up, but we are really close now. I have 3 girls who are 6, 9 and almost 12, so 3 years in between and then 6 years to Ruben. I've always thought that 3 years was a good gap, simply because by 3 they tend to be a bit more independent, can dress themselves, feed themselves and most importantly for me were potty trained by the time the next one was born. Of course that was what I wanted, but if you don't mind having more than one in nappies at a time etc, then go for it
Also like kte said I'd just go for the 4 bedroom and keep the spare rooms until you need them, saves having to move again. Can you tell I hate moving house?!
